Mic and Camera not working in UBUNTU

savvas999 · 12-08-2010, 12:10 PM

Hello!
Yesterday i installed UBUNTU Linux to my laptop, but my webcamera and mic not working in UBUNTU.
I checked sound settings, is all unmute. I downloaded GNOME Alsa MIxer, PulseAudio etc but nothing happened...

I read other topics, someone said to type that commands (may be helpful to understand any problem i have -?-)
"cat /proc/asound/card0/codec#* | grep Codec"--> Codec: Realtek ALC275
"cat /etc/modprobe.d/alsa-base" --> cat /etc/modprobe.d/alsa-base: No such file or directory

Anyone help me please?

Let's start with the sound card. Are you getting sound? I am assuming, yes.

So, open a terminal/console and enter

Code:

:~$ alsamixer

That is a commandline soundcard control. Your arrow keys will move you back and forth. The 'm' key will mute and unmute the different channels. You may find your mic is muted.

Yea im getting sound.
I entered command "alsamixer", but its all ok (mic etc)...

Any other suggestion please ?

It appears you have 2 soundcards

00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)
01:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1)

Do you have 2 cards listed in /proc/asound? Like /card0 and /card1

In the pic you posted for alsamixer you have the "playback" section listed. Yes it shows your mic's but there is no box under them to show them active. Fire up alsamixer again and press F5 to display all the channels on your card and see if your mic is really active.

Also press F6 to see the other sound card. It may be that you are trying to control the wrong one.

As for the camera, what are these in your lsusb output. What do you have plugged in?

To "sound preferences - hardware" shows that I have "High Definition Audio Controller - Digital Stereo (HDMI) Output" and "Internal Audio - Analog Stereo Duplex Input"
I also pressed F5 and F6. When I pressed F6 a box appeared which shows that I have 2 sound cards "HDA Intel" and "HDA Nvidia". I unmute anything to this cards... but nothing again...

I really don't care about web cam. My priority is to fixed the mic

Thanks for your help man.

OK so the first thing we have to determine is which sound card your mic is plugged into.

Is the machine a desktop or laptop? If it is a desktop can you take one of the cards out of it?

Another option is to try the mic and speakers in the other sound card. I do know that some soundcard drivers don't support the mic very well. Like mine for example, the mic will work but the results is full of static and there does not seem to be anything I can do about it.

Play with the controls in alsamixer for each card, one at a time and see which card controls the volume where your speakers are plugged in. Make sure the mike is enabled for that card. There are lots of sound recording apps in the repos. Install and try a couple of them.

The screen shot shows my mic's. Note that they have to be captured.

I did find this info about the camera (put on back burner for now)

Using lsusb, the webcam id is:
Bus 001 Device 003: ID 064e:2100 Suyin Corp.

The webcam is handled with module uvcvideo.ko

There may be a mic in the camera, I don't know the specs for it.

savvas999 · 12-10-2010, 09:58 AM

The machine is a laptop. In the other sound card, speakers / mic don't work.
Speakers are plugged in the RealTek ALC275 sound card.

I've tried everything, nothings worked... That sucks, forget it man, thanks anyway for your help...

rbees · 12-10-2010, 10:20 AM

Don't give up so easy.

Sometimes it takes me months to get something figured out.

So the realtek card, how is it hooked to the laptop?

savvas999 · 12-10-2010, 01:38 PM

What do you mean?

rbees · 12-10-2010, 02:51 PM

Laptop's typically have an onboard soundcard. If your laptop has two soundcards, how is the second one hooked to the machine? USB, PCcard, docking station?

savvas999 · 12-11-2010, 09:19 AM

Yea ur are right. But I dont know either why terminal or alsamixer shows that my laptop has two soundcards!
My laptop has an onboard soundcard (Realtek ALC275)

If the webcam does have a mic then it must have a soundcard to handle it. It may not be much of a soundcard but.....

How is the webcam hooked to the laptop? Unhook it, and run lspci again and see if they both show up.

Another thing that may have a soundcard in it is a tv adapter card. I know that some laptops have them onboard now. Does your laptop have that feature?

You get sound from your speakers, with alsamixer running you can play with the volume and tell which soundcard they are hooked to. Then you will know which one the mic should be hooked to. Is the mic captured on that card? If not then you will need to capture it. man alsamixer will tell you how to do so.

There are still lots of questions to answer. Have you tried any of the live-cd's to see if the mic works in them? What kernel are you using? Is your system fully patched? .......

And so we plod along. Every step is progress.

The only solution to make microphone work is to install linux-backports-modules-alsa-generic...

Just go to:

Menu / System / Administration / Synaptic Package Manager

And search and mark for installation:

linux-backports-modules-alsa-generic

tip: if you have multiple versions click on the first and read the description which should inform what name to install...

If after the reboot and mic mute is off, still does not work, just go to terminal and type:

sudo nano /etc/modprobe.d/alsa-base.conf

and add or change the following:

options snd-hda-intel model=auto enable=yes

Then Ctrl+X, type Y to write and exit, reboot and mic will work.

Bye and have lots of fun with Ubuntu (the best).
